To all whom it may concern:

Be it known that'I, JOHN HENRY FRALEY, a citizen of the United States, residing at Tiffin, in the county of Seneca and State of Ohio, have invented certain new and useful Improvements in Oil-Cups, of which the following is a specification.

VThe invention relates to an oil lcup, and more particularly to the class of feed .controls for oil cups.

The primary object of the invention is the provision of an oil cup of this character, wherein the contents thereof, such as oil for lubricating purposes, is controlled to regulate the feed thereof from the cup to the part to be lubricated, the control being effective by shocks and jars or vibrations incident to the part to be lubricated.

Another object of the invention is the provision of an oil cup of this character, wherein the controlling mechanism for the oil is constructed to prevent the choking of the delivery duct or passage for the oil and is self adjustable to regulate the proper feed of oil from the cup to the part to be lubricated.

A further object of the invention is the provision of a cup of this character, which is extremely simple in construction, possessingr but few parts, thoroughly reliable and eilicient in its purpose, durable, and inexpensive to manufacture.

With these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereunto appended.

In the accompanying drawing- Figure 1 is a side elevation of an oil cup constructed in accordance with the invention.

Fig. 2 is a vertical sectional elevation thereof.

Fig. 3 is a top plan view with the cap removed.

Fig. 4 is a horizontal sectional view taken on the line 4--4 of Fig. 2 looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates a portion of a part to be lubricated, and B the oil cup, which will be hereinafter fully described.

The oil cup comprises a cup shaped body 5 having at its closed bottom 6 a flange providing wrench engaging faces 7, whiley the opposite open end portion, externally thereof, is provided with screw threads 8 for the detachable fastening upon the body 5 of a removable cap 9 the rim being formed with anv external knurled surface 10 for permitting the easy fastening of the cap 9 upon the body 5 or its removal therefrom.

Interiorly of the body 5, centrally thereof, is a tubular column 11, suitablv fitted in the bottom Gand its passage or bore 12vconstitutesfan outlet or out way for oil, the said column 11 being reduced at its free end to form a nipple 13which terminates a slight distance'below the cap 9 when fastenedfupon the body 5 and loosely engaged upon this nipple 13 is a socket head 14, the head being preferably of inverted truncated conical shape with the socket therein for receiving the nipple 13 opening through the smaller end of said head and this smaller end 15 normally rests upon a shoulder 16 to close the passage or vent 12 in the column 11, the

nipple 13 contiguous to the shoulder 16 being formed with one or more orifices 17 so that upon the raising of the head 14 from the nipple 13 the passage or vent 12 will be in communication with the interior of the body 5 through said orifice 17 thereby permitting the flow of oil from the body 5 through the orifices 17 and passage 12 onto 0r about the part to be lubricated.

The body 5 at its bottom 6, centrally thereof, is formed with the usual external threaded neck 18 for connecting it to the said part or element as usual.

The head 14 is moved, or raised on the nipple 13 of the column 11 by vibration imparted to the cup, or from shocks or jars, to uncover the orifice 17 whereby the oil within the body 5 will be permitted to pass from said cup through the orifice 17 and passage 12 to the part or element to be lubricated. The head is at all times upon the nipple 13 and is limited in its movement by the cap 9 upon the body 5 of the cup and thus the passage 12 as well as the orifice 17 are protected to avoid clogging or choking thereof.

The cap 9 carries the usual gasket or washer 19 therein to render the said cap fluid tight when screwed down upon the cup.

From the foregoing it is thought that the construction and manner of operation of the oil cup Will be understood and therefore a more extended explanation has been l 1 tween thecolumn'and the interior of the body, a socketed head loosely seated on said omitted. l

What is claimed is:

1. In a lubricating oil cup comprising a cylindrical body, having a closed bottom, a screw threaded closure for the top of said body, a coaxially positioned tubular column having a reduced upper end extending in proximity to the said closure, said column being provided with a lateral aperturedefning an oil passage between the column and the interior of the body, a truncated socketed head loosely seated upon there duced Aupper endv of the said column and slightly spaced from the closure, said head normally closing the lateral' aperture but free to vibratebetween the closure and col'- umn to open said passage and screw threaded means for securing said cup to a part'to be lubricated.

2. In a lubricating oil cup comprising n.'

cylindrical body, having a closed bottom, a

closure for said body,a tubular column having a reduced upper'end forming a nipple for said column, in proximity to the said` closure, said nipple being provided with a lateral aperture delining an oil passage benpple and normally closing the top of said column and said lateral aperture, said head being free to vibrate on said nipple to open the said passage and screw threaded means for securing said cup to a part to be lubricated. v 3. In a lubricating oil cup comprising a body, a closure for said b0dy,a tubular column positioned within said body, a nipple formed on the upper end of said column and in proximity to the said closure, said nipple being provided with a lateral aperture defining an oil vpassage between the column and the interior yof saidl body, a head loosely seated on said nipple and normally closing the passage permitting vibration of said head between the column and the closure to open said passage, and means to secure said body to apart to be lubricated.

In'testimony whereof I hereunto aiiix my signature. c
